You are a soldier, planning to attack an enemy position. You have a foolproof strategy for taking positions held by ordinary enemies, which will get you killed if you use it on positions held by snipers. You can call in an airstrike that will reliably devastate the enemy position, but you'd prefer not to if you don't have to. Using an airstrike will overextend the army's air support; there's a % chance this will lead to a fellow soldier's death.
